摘要： The invention relates to a magnetically sensitive layer array (10, 20) with improved temperature and long-term stability for use in an GMR sensor element. Said array has at least two superimposed magnetic layers (14, 16, 18), a non-magnetic, copper-containing intermediate layer (15) that contains at least one precious metal being placed between said layers. The intermediate layer is particularly made of CuAgAu.

摘要： A magnetically sensitive component (30), in particular a sensor element, with at least two magnetoresistive layer systems (20) produced in regions on a substrate (10), is proposed. Here each of the layer systems (20) has at least one reference layer (2, 2'), at least one intermediate layer (3) adjacent to the reference layer (2, 2') and at least one detection layer (1) adjacent to the intermediate layer (3), and are connected as bridge resistors (R 2 , R 4 ) in an electrical circuit in the form of a Wheatstone bridge (21). Moreover, at least one of the reference layers (2, 2') has at least one magnetoresistive layer system (20), at least one first partial layer (2a, 2a') and at least one second partial layer (2b, 2b'), wherein the first partial layer (2a, 2a') exhibits a magnetisation (m 2 ) and the second partial layer is an antiferromagnetic partial layer (2b, 2b'). The magnetically sensitive component (30) is especially suitable for contactless and largely temperature-independent and offset-free recording of speeds and angles based on the GMR or TMR effect. In this connection it can also be used in the presence of strong external magnetic fields.

摘要： A circuit for ascertaining an external magnetic field, particularly for an angle sensor or angle transmitter, comprises first to fourth magnetoresistive elements (3a, 3b, 3c, 3d), which are connectible together into bridge with formation of two voltage dividers, and means for flexible connecting of the elements in such a manner that in a first operational state a first and a second element (3a, 3b) form a first voltage divider and a third and a fourth element (3c, 3d) form a second voltage divider and in a second operational state the first and the fourth element (3a, 3d) form a first voltage divider and the second and third element form a second voltage divider. It is thereby possible to obtain, with only four magnetoresistive elements, two field-related signals, such as sine and cosine signals, able to be evaluated to provide indications of angle over a range of 360{.

摘要： Production of a magnetically sensitive layer arrangement (10) comprises producing an arrangement of at least three subsequent layers (11, 12) made of alternating magnetic and non-magnetic material, and adjusting the temperature coefficient of the layer arrangement whilst the material of at least one layer is chemically modified.
